During a peripheral artery catheterization, the physician requested a tempo catheter 5f sim 2 100cm, after short manipulation the physician removed the catheter and then noticed a fracture in the distal end.The catheter was removed safely, and no part remained in the patient body.Then, after removing the catheter, he opened a second tempo catheter from the same lot and before inserting it into the introducer, while preparing the catheter, the physician noticed the catheter kinked.There were no reported patient injuries.The first catheter used was properly prepared and inserted over the wire into the sheath.To complete the procedure the physician used a cordis sim 1 catheter with no further problem.The devices were stored in their original packaging on the shelf in the cath lab.The devices were stored for more than a year.The devices were stored and handled per the instructions for use (ifu).The products were prepped properly according to the ifu.There were no difficulties experienced in prepping the devices.There were no anomalies noted to the devices when it was taken out of the packaging.There were no difficulties removing the products from the packaging.The catheters did not kink or bend at anytime prior to resistance/friction.There was no unusual force used at anytime during the procedure.There was no difficulty tracking through the vasculature.There was no resistance met while advancing or withdrawing the first tempo catheter 5f sim 2 100cm.The second tempo catheter 5f sim 2 100cm that was used kinked at the catheter body/shaft and wasn't broken.There are no pictures/procedural cd available of the damaged device.The patient is doing well and there is no damage done during the procedure or afterwards.There was no patient injury.Additional procedural details were requested but are unknown.

After further review of additional information received the following sections g4, g7, h2, h3 and h6 have been updated accordingly.During a peripheral artery catheterization, the physician requested a tempo catheter 5f sim 2 100cm, after short manipulation the physician removed the catheter and a fracture in the distal end was noted.The catheter was removed safely, and no part remained in the patient body.Then, after removing the catheter a second tempo catheter from the same lot was opened and before inserting it into the introducer, while preparing the catheter, the physician noticed the catheter was kinked.There were no reported patient injuries.The first catheter used was properly prepared and inserted over the wire into the sheath.To complete the procedure the physician used a cordis sim 1 catheter with no further problem.The devices were stored in their original packaging on the shelf in the cath lab.The devices were stored for more than a year.The devices were stored and handled per the instructions for use (ifu).The products were prepped properly according to the ifu.There were no difficulties experienced in prepping the devices.There were no anomalies noted to the devices when they were taken out of the packaging.There were no difficulties removing the products from the packaging.The catheters did not kink or bend at anytime prior to resistance/friction.There was no unusual force used during the procedure.There was no difficulty tracking through the vasculature.There was no resistance met while advancing or withdrawing the first tempo catheter 5f sim 2 100cm.The second tempo catheter 5f sim 2 100cm that was used kinked at the catheter body/shaft and did not crack.Additional procedural details were requested but are unknown.Two non-sterile diagnostic cardiology catheters cath tempo 5f sim 2 100cm were received for analysis inside a plastic bag.The units were numbered/ identified as unit one and unit two.Per visual analysis, the body/shaft, was noted to be cracked at 4.5 cm and at 10.5 cm from the tip.No other anomalies were found.The device was sent to sem analysis in order to identify the cause of the crack on the body/shaft.Sem results showed the separated area of the body/shaft presented with evidence of elongations and abrasions.Plastic deformation resulting in cup and cone-like shape, diameter reduction and tension marks were noted on the braidwires.Also, the separated areas of the braidwires presented with evidence of smearing.Furthermore, ductile dimples were found on the separated braidwire surfaces.The elongations found on the body/shaft material, the ductile dimples and plastic deformations as well as surface type of cup, resulting in a diameter reduction, are commonly associated with separations caused by material tensile overload.Therefore, it is assumed that the body shaft material was induced to a tensile force that exceeded the braidwire and body shaft material yield strength prior to the separation.No other issues were noted during sem analysis.A product history record (phr) review of lot 17624542 revealed no anomalies or non-conformances during the manufacturing and inspection processes that can be associated with the reported event.The phr review does not suggest that the event reported by the customer could be related to the manufacturing process.The reported ¿catheter (body/shaft)-cracked - in-patient¿ was confirmed due to the cracked condition on the device as received.However, the exact cause of the cracked device could not be conclusively determined during the analysis.The elongations found on the body shaft material, the ductile dimples and plastic deformations as well as surface type of cup, resulting in a diameter reduction, are commonly associated with separations caused by material tensile overload.Therefore, it is assumed that the body shaft material was induced to a tensile force that exceeded the braidwire and body/shaft material yield strength prior to the separation.As per the precautions in the instructions for use (ifu), ¿store in a cool, dark, dry place.Do not use if package is open or damaged.Do not use the catheter if the ¿use by¿ date on the package label has expired.Do not resterilize.Exposure to temperatures above 54c (130f) may damage the catheter.To prevent damage to the catheter tip during removal from the package, grasp the hub and withdraw the catheter.Exercise care when removing guidewires from multiple-curve catheters.Before use, flush all devices entering a blood vessel with sterile heparinized saline or a similar isotonic solution.¿ the device analysis, sem analysis report and phr review do not suggest that the event in case-(b)(4) experienced by the customer could be related to the manufacturing process.Therefore, no corrective or preventive actions will be taken at this time.
